Thanks, I haven't had more than 2 or 3 zaps all day...I don't know why it's only a day or two for me,.. but I will look at the site you recommended and I really appreciate your concern...my husband reminded me that I had an even weirder episode a few months ago but it was a patch on my arm. It wasn't red and it didn't shock me like the head ones do but it would just cause me a similar type of pain on the skin itself. The oddest part was that you couldn't see anything at all on my arm. Anyway, thanks for your concern and I will check out that site. Deby
